Bhagavad Gita · Chapter 3: The Path of Action

Bhagavad Gita 3.16

evaṃ pravartitaṃ cakraṃ nānuvartayatīha yaḥ | aghāyurindriyārāmo moghaṃ pārtha sa jīvati ||

One who does not follow the wheel that has been set turning in this way, Arjuna, who lives in sin and delights only in the senses, lives in vain.

Modern context

The wheel of giving and receiving keeps the world alive, and each person is asked to help turn it. Someone who only consumes and contributes nothing 'lives in vain'. The verse does not condemn enjoyment. It says that a life spent solely on one's own pleasure has missed its purpose.
